Abstract
Obstructive sleep apnea (OSA) occurs in up to 66% of Parkinson's disease (PD) patients, higher than in the general population. Although it is more prevalent, the relationship between OSA and PD remains controversial, with some studies confirming and others denying the relationship of OSA with some risk factors and symptoms in patients with PD. OBJECTIVE To determine the factors associated with OSA in PD patients com DP. METHODS A cross-sectional study was performed with 88 consecutive patients with PD from the outpatient clinic. Participants underwent clinical interviews with neurologists and a psychiatrist, assessment using standardized scales (Epworth Sleepiness Scale, Parkinson's Disease Questionnaire, Pittsburgh Sleep Quality Index and, for individuals with a diagnosis of restless legs syndrome/Willis-Ekbom disease, the International Restless Legs Syndrome Rating Scale), and video-polysomnography. RESULTS Individuals with PD and OSA were older and had less insomnia than those with PD without OSA. Regarding the polysomnographic variables, we observed a lower percentage of stage N3 sleep, a higher arousal index, and a higher oxygen desaturation index in those individuals with OSA, relative to those without OSA. In the multivariate analysis, only the percentage of stage N3 sleep and the oxygen desaturation index were significantly different. Besides this, most of the PD patients with OSA had a correlation with sleeping in the supine position (58% of OSA individuals). CONCLUSION The PD patients showed a high prevalence of OSA, with the supine position exerting a significant influence on the OSA in these patients, and some factors that are associated with OSA in the general population did not seem to have a greater impact on PD patients.
Highlights
Contrary to what was expected, no significant differences were observed between the groups with and without Obstructive sleep apnea (OSA), in the proportion of males, body mass index values, and scores on the Epworth Sleepiness Scale (Table 1)
We observed a lower percentage of non-rapid eye movement (NREM) stage N3 sleep, a higher arousal index, and a higher desaturation index in the individuals with OSA, in comparison with those without OSA (Table 2)
Analyzing the related factors with positional OSA, we found that supine-isolated OSA had a smaller number of apnea and hypopnea events than the other groups and, a lower oxygen desaturation index compared with others (Table 3)
Summary
Obstructive sleep apnea (OSA) occurs in up to 66% of Parkinson’s disease (PD) patients, higher than in the general population. It is more prevalent, the relationship between OSA and PD remains controversial, with some studies confirming and others denying the relationship of OSA with some risk factors and symptoms in patients with PD. RESUMO A Apneia Obstrutiva do Sono (AOS) chega a acometer até 66% dos pacientes com doença de Parkinson (DP), prevalência maior, portanto, que a da população geral. Conclusão: Pacientes com DP apresentaram prevalência elevada de AOS, a posição supina exerceu influência importante na AOS destes pacientes e alguns fatores que estão associados à AOS na população geral não mostraram impacto significativo nos pacientes com DP
